This is more growing up poor as opposed to weird family recipes..
Cheap tuna casserole - cook a box of Kraft mac and cheese, leave it in the pot, dump in a can of tuna and a can of mushy canned peas, mix and eat
"Hash" - brown some hamburger meat with onions and bell peppers, cut up 3 or 4 potatoes, throw it all in a soup pot, cover in water and cook until potatoes are mushy and bell peppers turn to slime, add tons of salt and pepper because my mom and step-dad smoked like chimneys and had no taste buds
Lays potato chip sandwiches, just chips and bread
Warm tortillas with butter (well, margarine, who could afford butter?) (and no, we did not sprinkle sugar and cinnamon on it, that's why God made cinnamon toast)
An open face grilled cheese? Piece of bread, slice of cheese on top, pop in the toaster oven until cheese just starts to turn brown, ate that everyday after school
My step-grandma, bless her she was so country, used to make this pseudo-Watergate salad, lime green jello mixed with cottage cheese, pineapple chunks, pecans, shredded carrots and raisins - ugh Did I eat it, yeah
My mom used to make homemade salad dressing, miracle whip, ketchup, a little worcestershire sauce and garlic powder mixed together, 500 islands maybe?
